Bucks. Dough. Bread. Whatever you call it, American money has changed a lot over the years. Before the 1860s, gold and silver coins were the only currency produced by the U.S. government. But that changed during the Civil War (1861-1865). President Abraham Lincoln needed money to pay Union troops, but there was a shortage of coins. Enter the dollar bill. Here are some fascinating facts about our paper money.

Real or Fake?
Some people print fake bills and try to pass them off as real. That’s called counterfeiting, and it’s illegal. U.S. bills have security features to make them harder to counterfeit, including special ink colors. Here are some ways to tell if your dough is real.
